Pop-up windows Frequently, when you select an option from a screen, a smaller screen opens and is
superimposed over the original screen. This additional screen is called a “pop-up” window. It
may provide information or require data input. In either case, only command choices
(buttons) appearing within the pop-up window are active at that time. You cannot select an
icon button when a pop-up window is open.

Drop-down menus A “drop-down” menu reveals settings for you to choose from. You can easily identify a drop-
down menu by its characteristic arrow positioned within the command button. The current
selection is visible to the left of the arrow. To open the menu and reveal the options, touch the
current selection
. To change the selection, touch any item on the drop-down menu. The menu
will collapse. To keep the original selection, simply touch the top selection.
Examples of HFA II drop-down menus are found on the Screening Parameter Setup screen
shown below. A closer look at the Test Speed drop-down menu reveals the two available
selections, NORMAL and SLOW.
